Prevent integer overflow within the integer-datetimes version of
TimestampTzPlusMilliseconds. An integer argument of more than INT_MAX/1000milliseconds (ie, about 35 minutes) would provoke a wrong result, resultingin incorrect enforcement of statement_timestamp values larger than that.Bug was introduced in my rewrite of 2006-06-20, which fixed some otheroverflow risks, but missed this one :-( Per report from Elein.
